Question 1 Heat is the measure of thermal energy that flows from one object to another driven by a difference in temperature. Question 1 options: True False Question 2 Temperature is related to the average kinetic energy of the molecules.

A covalent chemical bond is one in which outer-shell electrons of two atoms are shared so as to satisfactorily fill the outer electron shells of both atoms. protons and neutrons are shared by two atoms so as to satisfy the requirements of both atoms.

To break a chemical bond, energy must be (1) absorbed (2) destroyed (3) produced (4) released
